If there is anyone still out there in Cube Land, I have successfully just put a 120GB SSD in my trusty Cube in place of a 128GB HD, which is now mounted in an external USB box.. The SSD was supplied with an SATA to ATA adapter by OWC. It was not the easiest thing to fit, simply because the sled to which it was affixed was not really meant for a Cube HD slot. The card plus sled simply sits at an angle resting inside the drive bay. This also further reduces load on the VRM. My Cube already had a dual 1.5GHz CPU (PowerLogix from OWC) and a DVD-R (Matshita UJ-815) so it seemed worth a last hurrah! that was also not too expensive and keeps the machine useful. I still use it with an HP Scanjet scanner that I can’t transfer to a new Mac Pro. Start-up time is amazing, too. Steve
